SATELLITE ANALYSIS AND TRENDS...A TRAINING BAND OF PRECIP STRETCHES FROM
SW-NE ACROSS LA/MS/AL/N GA CURRENTLY CONSISTING MOSTLY OF STEADY MOD
RAINS WITH ISOLATED CONVECTIVE ELEMENTS EMBEDDED. S/WV ENERGY CONTINUES
TO PUSH NE ACROSS CENTRAL/NE AL AND N GA WITH A BROAD CLOUD SHIELD THAT
HAS EXHIBITED A CLOUD TOP WARMING TREND OVER THE PAST FEW HRS. BROAD DEEP
LAYERED SWRLY FLOW ACROSS THE REGION IS ORIENTED ALONG A RICH MOISTURE
PLUME THAT ORIGINATES SW OF MEXICO CONNECTING TO A TROPICAL WAVE WITH PW
VALUES OF 1.6-1.8" IN GNRL OVER THE DISCUSSION AREA. EVEN GIVEN THE HIGH
PW VALUES..VERY LIMITED INSTABILITY ALONG THE PRECIP AXIS IS LIMITING
INTENSITY OF ANY CNVCTN. ONLY WITHIN THE WARM SECTOR OVER SE LA DOES SPC
MESOANALYSIS INDICATE ANY NOTABLE SBCAPE. GREATEST SFC CNVG IS ANALYZED
OVER SW/S CENTRAL MS..JUST AHEAD OF THE SLOWLY ADVANCING SFC LOW/FRONTAL
BNDRY. THIS AREA OF CNVG IS COLOCATED WITH DVGNC ALOFT AS INDICATED BY
THE EXPERIMENTAL MESOSCALE SATL WIND PRODUCT.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0800-1100Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...MOD-LOCALLY HVY RAINS WILL CONTINUE ALONG THE
SW-NE PRECIP AXIS FOR AT LEAST THE NEXT FEW HRS. SOME SHWR/WEAK TSTORM
DVLPMT MAY STILL OCCUR WITHIN THE WARM SECTOR AND LIFT NWD MERGING
INTO THE AXIS OVER S MS DURING NEXT HR OR TWO. UPSTREAM HEIGHT FALLS
ASSCD WITH THE DIGGING S/WV TROF OVER W TX/MEXICO HAS STARTED TO INCRS
DOWNSTREAM RIDGING OVER THE NE TX COAST/W LA PER WV IMAGERY AND PRECIP
WORKING NWD ACROSS THESE AREAS. THERE ALSO APPEARS TO BE A MID-LVL S/WV
IMPULSE WITHIN THE FLOW ALONG THE TX COAST THAT SHOULD HELP TO BOTH PUSH
THE TRAINING AXIS OF PRECIP NEWD AND POSSIBLY AIDE IN AN EXPANSION OF
LGT-MOD PRECIP OVER N LA/S AR/CENTRAL AND N MS LATER THIS MORNING WITH
POTENTIAL LIMITATIONS BEING BEST MOISTURE AXIS TO THE SE AND LIMITED
INSTABILITY. UNTIL THEN..RAINRATES GNRLY SHOULD REMAIN BELOW 1"/HR BUT
SVRL HRS OF TRAINING MOD-LOCALLY PRECIP COULD RESULT IN AMOUNTS OF 1-2".
